We are one of those. Using 12.0.26S5 on a 12406, we had to trade in
the following features to get an aggregate link (etherchannel, in cisco speak):

- access lists (yuk! - no more bogon filtering on a public exchange)
- mac accounting (yuk! - no more traffic statistics for peerings)
- ipv6
- netflow
